3. explain how tectonic plate movement could create another supercontinent like pangaea.

If tectonic plates, which carry different continents, collide, they could create a supercontinent, like the pangea.

Explanation:

Due to the movement of tectonic plates, which generate seismic and volcanic activities, the pieces of earth were dividing and eventually drifted away over the years, thus separating the continents. Because of this movement, the continents can unite again, creating a supercontinent. That is because, the continents are on top of the tectonic plates and these plates are in constant movement. If two plates carrying two different continents collide, they can unite these continents into one.

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.
